Write access is only in omap3_evm_get_revision() which in turn only gets called in misc_init_r(), i. e. after relocation. Read access is only in get_omap3_evm_rev() [which is not called outside this file and thus should be made static!] which gets called only in omap3_evm_need_extvbus() which gets acalled only in musb_platform_init(), i. e. during USB init. This should be safe. You could try out what happens if you make get_omap3_evm_rev() static...
